Abstract

The LiFePOVC battery has been widely used in many fields, and its safety problems are gradually attracting widespread concern. In this paper, two kinds of LiFePO4/C batteries with 25 Ah and 200 Ah were taken as research objects. The thermal runaway phenomena of two batteries were analyzed, and the difference of thermal runaway phenomena between two batteries were compared. The results show that the safety valve of the 200 Ah battery ruptures earlier and the thermal runaway occurs earlier under the same overcharge rate. The work provides a reference for the protection design of LiFePO4/C batteries.
